Various built-in sensors enable interacting with mobile devices beyond the screen. So-called mobile device-based interaction techniques are characterized by movements and positions in real space, e.g. twisting the device to switch between front and rear camera or pouring photos from one device into another for sharing. Although interactions should be as intuitive as possible, it is often necessary to introduce them, especially if they are complex or new to the user. Applications have to present interactions appropriately so that users can understand and use them easily. We conducted a user study to investigate the suitability of onboarding tutorials for mobile device-based interaction techniques. Results show that these types of tutorials are insu_cient for communicating mobile device-based interactions, mainly because of their spatial and tangible characteristics but also their collaborative and representative interdependencies. Based on this, we propose suggestions for improving the design of tutorials for device-based interactions with mobile phones.

Syftet med denna studie var att undersöka vilken inställning elever och idrottslärare har till att använda mobiltelefoner, film och bloggar i samband med undervisningen i ämnet idrott och hälsa. Urvalsgruppen bestod av 225 grundskole- och gymnasieelever samt 5 lärare fördelat på 5 skolor i Skåne. De metodologiska tillvägagångssätten utgjordes av intervjuer med lärarna och en enkätundersökning med eleverna. Resultaten har analyserats med utgångspunkt i Roger Säljös vidareutveckling av Lev Vygotskijs sociokulturella perspektiv på lärande, samt Thomas Ziehes teori om kolliderande livsvärldar. Vidare har resultaten ställts i relation till tidigare resultat inom forskningsfältet. Undersökningen visar att både lärare och elever, generellt sett, har en positiv inställning till de IKT-praktiker och användningsområden som varit i fokus. Eleverna var, till skillnad från lärarna, emellertid negativa till att använda bloggar i samband med undervisningen i ämnet idrott och hälsa. Resultatet pekar på att elever som använt en IKT-praktik är mer positivt inställda till praktiken än de elever som inte använt praktiken. / The purpose of this study was to examine the attitude amongst students and physical education teachers towards using mobile phones, films, and blogs during physical education teaching. The selection group consisted of 225 students and 5 teachers from 5 schools in the Skåne region, Sweden. Questionnaires have been issued to the students and the teachers have been interviewed. The results have been analyzed with the help of Roger Säljös further development of Lev Vygotskij’s sociocultural perspective on learning, and Thomas Ziehe’s theory on colliding realities. Furthermore, the results have been put in relation to earlier studies within the research field. The results show that both students and teachers, generally, have a positive attitude towards the studied ICT-practices and uses. The students did however, unlike the teachers, have a negative attitude to using blogs in physical education. The results indicate that students who have used an ICT-practice have a more positive attitude towards that practice than students that haven’t used it.

This study investigates the possibilities for an end-user mobile application that increases access to healthcare in rural communities in Mozambique. The country is facing multiple healthcare-related challenges, including a high prevalence of infectious diseases and a low density of physicians. Improved accessibility to mobile phones opens up the possibility of using mobile health applications to improve health outcomes for people in the country. A literature review, interviews, and questionnaires are conducted to better understand the country, its healthcare system, and its people. Based on the collected data, requirements are developed for a mobile health application that provides healthcare information to patients. The requirements are evaluated based on user testing and the framework tool Dynamics of Social Practice. The perceived usefulness and material prerequisites suggest that the application could get a foothold in Linga Linga and similar rural areas, provided that it’s accompanied by training and redesigned to facilitate ease of use. In the future, the requirements’ technical, operational and economic feasibility could also be investigated. / Denna studie undersöker möjligheterna för en slutanvändarmobilapplikation, som ökar tillgången till sjukvård på landsbygden i Moçambique. Landet står inför flera hälso- och sjukvårdsrelaterade utmaningar, inklusive en hög förekomst av infektionssjukdomar och en låg täthet av läkare. Förbättrad tillgänglighet till mobiltelefoner öppnar för möjligheten att använda mobila hälsoapplikationer för att förbättra hälsopåföljder för människor i landet. En litteraturstudie, intervjuer och enkäter genomförs för att bättre förstå landet, dess sjukvårdssystem och dess folk. Baserat på den insamlade datan utvecklas krav på en mobil hälsoapplikation som ger hälsoinformation till patienter. Kraven utvärderas utifrån användartester och ramverktyget Dynamics of Social Practice. Den upplevda användbarheten och de materiella förutsättningarna tyder på att applikationen kan få fotfäste i Linga Linga och liknande landsbygdsområden förutsatt att den åtföljs av utbildning och omdesignas för att underlätta användarvänligheten. I framtiden kan även kravens tekniska, operativa och ekonomiska genomförbarhet undersökas.

The objectives of this work were to investigate, design and implement Multiple-Input Multiple-Output (MIMO) antenna arrays for mobile phones. Several MIMO antennas were developed and tested over various wireless-communication frequency bands. The radiation performance and channel capacity of these antennas were computed and measured: the results are discussed in the context of the frequency bands of interest. A comprehensive study of MIMO antenna configurations such as 2 × 1, 3 × 1, 2 × 2 and 3 × 3, using polarisation diversity as proposed for future mobile handsets, is presented. The channel capacity is investigated and discussed, as applying to Rayleigh fading channels with different power spectrum distributions with respect to azimuth and zenith angles. The channel capacity of 2 × 2 and 3 × 3 MIMO systems using spatial polarisation diversity is presented for different antenna designs. The presented results show that the maximum channel capacity for an antenna contained within a small volume can be reached with careful selection of the orthogonal spatial fields. The results are also compared against planar array MIMO antenna systems, in which the antenna size considered was much larger. A 50% antenna size reduction method is explored by applying magnetic wall concept on the symmetry reference of the antenna structure. Using this method, a triple dual-band inverted-F antenna system is presented and considered for MIMO application. Means of achieving minimum coupling between the three antennas are investigated over the 2.45 GHz and 5.2 GHz bands. A new 2 2 MIMO dual-band balanced antenna handset, intended to minimise the coupling with the handset and human body was proposed, developed and tested. The antenna coupling with the handset and human hand is reported in terms the radiation performance and the available channel capacity. In addition, a dual-polarisation dipole antenna is proposed, intended for use as one of three collocated orthogonal antennas in a polarisation-diversity MIMO communication system. The antenna actually consists of two overlaid electric and magnetic dipoles, such that their radiation patterns are nominally identical but they are cross-polarised and hence only interact minimally.

Zeals är en mobil applikation där användaren tillåts att kollaborativt uppleva förväntan och erinran inför och efter en händelse. Genom att användaren bidrar med media som hon själv definerat som relevant för händelsen kan mobiltelefonen fungera som ett medium där kopplingar och relevans är upp till användaren. Parallellt har ett designverktyg för användarjämförelser tagits fram - Persona Activity Framework. PAF syftar till att genom ett scenario visa skillnader och likheter mellan tilltänkta användare. / This master thesis in interaction design deals with two major scopes. First, it will describe how a design concept regarding events is initiated. Second, and parallel, a practical tool for user representations will be formed and used to illustrate a foundation for design. By providing examples of projects related to how anticipation and recollection can be experienced we highlight our work area. In addition to this, we present tools that we consider beneficial regarding user insights. Out of these two fields we describe a process where a mobile phone application is created situated within industrial borders. The result of this process consequently consist of two parts each depending on the other. The application, Zeals, demonstrates both how anticipation and recollection can be experienced. The second part of the end result, PAF, demonstrates how we have represented users and concludes that it can be used in other projects as well. Hence, our final result needs to be interpreted depending on design approach and it’s nature.

Access, use and ownership of mobile phones is increasing rapidly in Tanzania, as in the rest of Africa. It is estimated that a staggering 97% of the population are able to access a mobile phone, according to a study carried out by the Centre for Economic Policy Research and Vodafone. The growing number of people using mobile phones has led to optimism and speculation regarding its effect on economic and social development. Expectations from mobile phones are high and it has already been coined as Africa’s PC. Expectations are further fuelled by sensationalist headlines in the media such as, Mobile phones join war on African poverty, The mobile revolution sweeps across Africa or Cell phones the latest tool in Africa's fight against HIV and is shaping the discourse on mobile phones for development (M4D). This study was carried out between January and March 2010 in Dar Es Salaam, Tanzania and funded by SPIDER, The Swedish Program for ICT in Developing Regions and commissioned by Femina HIP (Health Information Project) a Tanzanian multimedia civil society initiative that expressed desire for research to be conducted on mobile phones and SMS (Short Messages Service) in Tanzania. This paper contains data from three group interviews and one quantitative survey that was completed by 97 youths. The empirical material gathered is discussed in relation to empowerment and participation, two concepts that have become mainstreamed in development theory and practice and in communication for development. The paper is structured as following. The first chapter provides the aim and purpose of the study as well as its delimitations. The second chapter discusses mobile phones for development while critically looking at the M4D and ICT4D discourse. Also incorporated in this chapter is an example of a mobile phone project that was started in Bangladesh in the late 1990s and is used as an example to represent the empowerment narrative in M4D. A short discussion on this sentiment will conclude the second part. In the third chapter I present my theory. I take a critical look at empowerment and participation, two concepts that have gained, one can say, a moral authority that effectively hides power relations amongst participants, facilitators and donors in development projects. In the fourth chapter I discuss my methodology and how I gathered my material. In the fifth part I present my data and in the last chapter I analyse the empirical material by applying the framework of participation and empowerment. I also discuss what an organisation such as Femina HIP could gain from incorporating mobile phones into their communication strategy.

Arbetet har genomförts med målet att skapa ett mervärde för Sony Ericssons produkter, utan att fokusera på telefoner. Vi har undersökt hur man kan öka användarens band till en teknologisk produkt som man alltid bär med sig. Vi har, genom att anordna en workshop, studerat användare och deras attityd gällande personalisering av mobiltelefoner. Vidare har vi besökt Milano och Berlin, och studerat hur mobiltelefoner kommuniceras hos återförsäljare och hur de används, för att få ett globalt perspektiv. Studierna har resulterat i att vi funnit en brist i hur personliga teknologier svarar mot människors känslor. Vi har baserat på detta skapat ett koncept vi kallar Selectíf som innebär en serie riktlinjer, eller kriterier för att skapa tillbehör till mobiltelefoner. Dessa tillbehör skall ta större hänsyn till emotionella aspekter och fokusera mindre på att vara funktions orienterade. Selectíf-produkter sätter känslorna i främsta rummet och skapar därmed ett mervärde baserat på emotionella band. / We have in this thesis studied the area of emotive design as a way to create a stronger user experience. Functionality and features are still important to break new grounds and develop artifacts that can make our life easier, but the value of the product must beconsidered in a new way and communicated on new level, an emotional level.We have within the thesis, in collaboration with Sony Ericsson,investigated how emotions can be evoked by personal technologies.The human computer interaction is today so advanced that we might not always reflect over the impact the technology has on us. Our personal technology is getting more sophisticated which could allow stronger emotional bonds between the user and a device. What we have created is a concept for designing what we call emotional triggers.To find out what triggers users’ emotions towards technologyin order to create an added value, we have studied the relationshipbetween users and their mobile phones. These studies included a workshop where we aimed to find out how users perceive their mobile phone and also how willing they are to personalize it.Furthermore we conducted trend research in Berlin and Milan to see international differences in mobile usage and also tocompare it to other industries such as the fashion industry.The result is a concept we call Selectíf. The concept is a set of design criteria for designing add-ons that are made to illustratemore emotional values of a technical device. The concept is based on the notion of a series of add-ons and we have also createda first prototype, called Selectíf no1 based on the criteria.The prototype focuses less on technology and more on a user’s emotional needs and illuminates how personal technologies canbe designed to be more emotive and thereby create a stronger user experience.

The main purpose of this study was to examine the use of mobile phones by Generation Y students in the city of Johannesburg in order to increase understanding of this segment's consumer behaviour. Generation Y is an important market segment in that it is making more independent purchase-related decisions and has a large amount of disposable income. The primary data for this study is based on focus group interviews and a quantitative study of a sample of 200 Generation Y tertiary students. Some of the findings are as follows: * Generation Y's use of mobile phones: Generation Y respondents have owned a mobile phone for between three to five years; the majority own Nokia mobile phones, are on prepaid packages and are not big spenders on airtime; furthermore, SMS is seen as the most cost-effective way to communicate. * Competition in the mobile phone market: The perceptions of this segment are that Vodacom is the "cool" operator, MTN is the most "expensive" network operator and Cell C is "cheap and youthful". * Mobile phone brand awareness: Nokia was the most cited brand of mobile phone and was found to be the first choice of many of the respondents. Samsung was reported as the second most cited brand with Motorola, Siemens and Sony Ericsson following. The results have implications for network providers, handset manufacturers and marketers alike as they will ultimately improve these stakeholder's chances of marketing effectively to this dynamic youth market. / Business Management / M.

Thesis (MA)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: This thesis aims to make a contribution to the field of literature study in foreign language teaching. It investigates the practical implications of theories such as Michael Dobstadt‟s Didaktik der Literarizität and Claire Kramsch‟s symbolic competence. It specifically looks at how these approaches to literature can be implemented in the elementary levels (A1 and A2) of foreign language teaching. Furthermore, the range of possibilities that mobile phones offer for the foreign language learning environment are explored. Suggestions are proffered as to how the inclusion of mobile phones, as educational tools, can support the successful implementation of Dobstadt and Kramsch‟s theories in the foreign language classroom. On the basis of the theory, two sets of lesson plans are developed for high school beginner level German classes in South Africa; the lesson plans serve as examples of how the theories of Dobstadt and Kramsch can, on beginner level and in conjunction with the use of mobile phones, be implemented in practice. / AFRIKAANSE OPSOMMING: Hierdie tesis poog om ʼn bydrae te maak tot die literatuur van vreemdetaal-onderrig. Die praktiese implikasies van teorieë soos dié van Michael Dobstadt se Didaktik der Literarizität en Claire Kramsch se symbolic competence word ondersoek. Daar word spesifiek gekyk na hoe sulke benaderings tot literatuur op beginnervlak (A1 en A2) van vreemdetaal-onderrig geïmplementeer kan word. Verder word die trefwydte van moontlikhede wat selfone vir vreemdetaal-onderrig bied, ondersoek. Voorstelle word gemaak oor hoe die gebruik va n selfone, as opvoedkundige hulpmiddels, die implementering van Dobstadt en Kramsch se teorieë in die vreemdetaal-klaskamer kan ondersteun. Vanuit „n teoretiese uitgangspunt word twee stelle lesplanne vir Duitse klasse op hoërskool-beginnervlak in Suid-Afrika ontwikkel as voorbeelde van hoe die teorieë van Dobstadt en Kramsch, op beginnervlak en in samewerking met die gebruik van selfone, in die praktyk geïmplementeer kan word.

Dans ma thèse, je me sers de modèles de recherche solides pour répondre à des questions importantes de politique publique. Mon premier chapitre évalue l’impact causal de l’allégeance partisane (républicain ou démocrate) des gouverneurs américains sur le marché du travail. Dans ce chapitre, je combine les élections des gouverneurs avec les données du March CPS pour les années fiscales 1977 à 2008. En utilisant un modèle de régression par discontinuité, je trouve que les gouverneurs démocrates sont associés à de plus faibles revenus individuels moyens. Je mets en évidence que cela est entrainée par un changement dans la composition de la main-d’oeuvre à la suite d’une augmentation de l’emploi des travailleurs à revenus faibles et moyens. Je trouve que les gouverneurs démocrates provoquent une augmentation de l’emploi des noirs et de leurs heures travaillées. Ces résultats conduisent à une réduction de l’écart salarial entre les travailleurs noir et blanc. Mon deuxième chapitre étudie l’impact causal des fusillades qui se produisent dans les écoles secondaires américaines sur les performances des éléves et les résultats des écoles tels que les effectifs et le nombre d’enseignants recruté, a l’aide d’une stratégie de différence-en-différence. Le chapitre est coécrit avec Dongwoo Kim. Nous constatons que les fusillades dans les écoles réduisent significativement l’effectif des élèves de 9e année, la proportion d’élèves ayant un niveau adéquat en anglais et en mathématiques. Nous examinons aussi l’effet hétérogene des tueries dans les écoles secondaires entre les crimes et les suicides. Nous trouvons que les fusillades de natures criminelles provoquent la diminution du nombre d’inscriptions et de la proportion d’élèves adéquats en anglais et mathématiques. En utilisant des données sur les élèves en Californie, nous confirmons qu’une partie de l’effet sur la performance des élèves provient des étudiants inscrits et ce n’est pas uniquement un effet de composition. Mon troisième chapitre étudie l’impact des cellulaires sur la performance scolaire des élèves. Le chapitre est coécrit avec Richard Murphy. Dans ce chapitre, nous combinons une base de données unique contenant les politiques de téléphonie mobile des écoles obtenues à partir d’une enquète auprès des écoles dans quatre villes en Angleterre avec des données administratives sur la performance scolaire des éleves. Nous étudions ainsi l’impact de l’introduction d’une interdiction de téléphonie mobile sur le rendement des éleves. Nos résultats indiquent qu’il y a une augmentation du rendement des éleves après l’instauration de l’interdiction des cellulaires à l’école, ce qui suggère que les téléphones mobiles sont sources de distraction pour l’apprentissage et l’introduction d’une interdiction à l’école limite ce problème. / In my thesis, I use compelling research designs to address important public policy issues. My first chapter estimates the causal impact of the party allegiance (Republican or Democratic) of U.S. governors on labor market outcomes. I match gubernatorial elections with March CPS data for income years 1977 to 2008. Using a regression discontinuity design, I find that Democratic governors are associated with lower average individual earnings. I provide evidence that this is driven by a change in workforce composition following an expansion in employment of workers with low and medium earnings. I also find that Democratic governors cause a reduction in the racial earnings gap between black and white workers through an increase in the annual hours worked by blacks relative to whites. My second chapter analyze how shootings in high schools affect schools and students using data from shooting databases, school report cards, and the Common Core of Data. The chapter is co-written with Dongwoo Kim. We examine schools’ test scores, enrollment, and number of teachers, as well as graduation, attendance, and suspension rates at schools that experienced a shooting, employing a difference-in-differences strategy that uses other high schools in the same district as the comparison group. Our findings suggest that homicidal shootings significantly decrease the enrollment of students in Grade 9, and reduce test scores in math and English. We find no statistically significant effect for suicidal shootings on any outcome variables of interest. Using student-level data from California, we confirm that some of the effects on student performance occur as a result of students remaining enrolled and not only due to changes in student body composition. My third chapter investigates the impact of school mobile phone policy on student performance. The chapter is co-written with Richard Murphy. Combining a unique dataset on autonomous mobile phone policies from a survey of schools in four cities in England with administrative data, we investigate the impact of imposing a mobile phone ban on student performance. Our results indicate an improvement in student results after a school bans the use of mobile phones; this suggests that mobile phones distract learning and imposing a ban limits this problem.
